Gem::FilePermissionError: You don't have write permissions for the /var/lib/gems/3.1.0 directory.

Thank you for contributing to the
rubygems repository, and specifically to
RubyGems.

Describe the problem as clearly as you can

While trying to install prereqs for blue_hydra on kali linux I run into an issue where bundle install does not work which means I am unable to download sqlite3 (one of the required dependencies). The reason it gives me is that there is a lock on one of the gemfiles and I don't have permissions to write. I've tried every update and command online that I can find, but nothing seems to work.

Did you try upgrading RubyGems?

tried to update ruby gems and received this error message: ERROR: Your RubyGems was installed trough APT, and upgrading it through RubyGems itself is unsupported. If you really need the latest version of RubyGems (tip: you usually don't), then you need to install RubyGems (and Ruby) manually, maybe using tools like ruby-install, rvm, etc.

Post steps to reproduce the problem

338 sudo apt-get update
339 sudo apt-get install git-core curl zlib1g-dev build-essential libssl-dev libreadline-dev libyaml-dev libsqlite3-dev sqlite3 libxml2-dev libxslt1-dev libcurl4-openssl-dev python-software-properties libffi-dev
340 git clone https://github.com/rbenv/rbenv.git ~/.rbenv
341 echo 'export PATH="$HOME/.rbenv/bin:$PATH"' >> ~/.bashrc
342 exec $SHELL
343 git clone https://github.com/rbenv/ruby-build.git ~/.rbenv/plugins/ruby-build
344 echo 'export PATH="$HOME/.rbenv/plugins/ruby-build/bin:$PATH"' >> ~/.bashrc
345 exec $SHELL
346 rbenv install 2.3.1
347 rbenv global 2.3.1
348 ruby -v
349 gem install bundler
350 rbenv rehash
351 ruby -v
352 bundle install
353 gem install rubygems-update
431 sudo gem install rubygems-update
432 update_rubygems
433 gem update --system

Which command did you run?

bundle install

What were you expecting to happen?

I expected it to install all the needed dependencies, but instead gave me an error message saying it was unable to install sqlite3 do to not having write permissions on the /var/lib/gems/3.1.0 directory.

What actually happened?
